FLUSHING APPARATUS FOR WATERCLOSETS,.&C.

SPECIFICATION forming part of Letters Patent No. 299,606, dated June 3, 1884.-.

Application filed January 26, 1884.

To all whom, it may concern.-

Be it known that I, HENRY C. WEEDEN, of Boston, in the county of Suffolk and State of Massachusetts, a citizen of the United States, have invented certain new and useful Improvements in Flushing Apparatus for Water-Closets, of which the following is a specification.

My invention relates to improvements in apparatus for flushing water-closets and similar structures, and has for its object to provide mechanism whereby the production of this result is materially simplified and obtained with a smaller number of working parts than have heretofore commonly been required.

I will now proceed to describe a structure embodying my invention in the formnow best known to me, and illustrated in the accompanying drawing, which is a vertical section of my apparatus.

H is a iiushing tank or ch amber, from which aV conduit, B, leads to the wat-er-closet or other structure to be iiushed.

C represents a second chamber, into which enters a pipe from the street-main or other head of water from which the supply is obtained. This chamber C is also arranged to communicate with the chamber A, for the purposes and under the circumstances hereinafter explained.

E represents a rod, packed at one end, F, or at a point above the introduction of the water-supply through D, as shown, so as to form a water-tight piston or plunger within the chamber C, and also provided with valves G H, adapted to close, respectively, the passage from the chamber C to the chamber A and that from the chamber A to the conduit B.

J K represent a lever arm, one Y end of which is connected by means of the connection L with the hinged seat of the closet or the hinged standard of the urinal to be ilushed, such 'seat or standard being constructed in this respect in the well-known manner; or the connection L may terminate in a hand-pull. I prefer, however, to connect it with the seat or standard, so that it may be operated by the weight of the person using the closet or urinal, as will hereinafter be explained. This lever J K acts against an extension of the rod E, before referred to, so that the rod will be forced down when the lever is depressed.

(No model.)

Theoperation of the apparatus is as follows: The drawing represents the position of the parts when the head of water is on and before the closet .is occupied. The area of the packing or piston F, which surrounds the rod E above the entrance of the water-pressure, being greater than the area of the passage Vfrom the chamber C into the chamber A, it is obviousV that the unbalanced pressure upon the valve F will hold 'the valve G tightly against and thereby close the mouth of the passage from the chamber C to the chamber A, and no water will pass through.v When the closet or urinal is occupied, the weight of the occupant, pulling down the lever K, depresses the rod E until its lower packing, H, is brought against and closes the passage from the chamber A into the conduit B. This same movement, however, carries the valve G away from its seat, and permits the water to flow into A until A is full, and this state of things continues as long as the rod E is held down. urinal leaves it, or when the strain upon the connection L ceases, the unbalanced pressure upon the valve F raises the rod E until it resumes its first position, or that shown in the drawing. This opens the lower passage from the chamber A into the conduit 13,-leadingto the closet or urinal, and the contents of the Vchamber A are discharged and form a flush,

while the apparatus remains in its normal position until the closet is again occupied. When 'the rod E is depressed, air may enter the chamber C below the valve F from the chamber A, the escape of which is provided for by the valved air-passage f through the plunger F, as shown. In the same manner the passage of air to or Vfrom the chamber A, when it is desired to fill the latter vwith water or to empty its contents, is allowed forby a similar valved air-passage, a, as shown. Any leakage of water by the valvel F or past the valve of the air-passagef or of the air-passage a is provided for by the overiiow-pipe M. A stopcock, N, of ordinary construction, may be inserted in the supply-pipe, as shown, to cut off the whole supply of water from the apparatus' when this is for any reason desirable-as, for example, in the case of repairs to the apparatus, 8vo. The rapidity of the ushing-flow When the occupant of the closet or IOO from the chamber A may be governed by adjusting the distance apart of the valves G and H upon the rod E. For this purpose I make the valve G movable or adjustable upon the rod E, as shown. The relative area of the upper packing or piston-head, F, and the aperture or conduit between the chambers C and A should be such that the excess of pressure upon the packing or piston-head F will insure a good closure of the passage by the valve G when the apparatus is in the position shown in the figure.

It will be observed that by means of my present invention I am enabled to dispense with the ball-cock and iioat commonly made use of for opening and closing the passage from the water-supply pipe into the tank or cistern, and also practically to dispense with the eistern itself by substituting for it the chamber C, of much smaller extent. Furthermore, it will be observed that water does not stand in the chamber A,(the capacity of which need be no larger than is required by the amount of water used for each iush,) except for a very short time while the closet is actually in use.

I claim* l. A flushing device for water-closets, urinals, and similar structures, consisting of a water-chamber connected with the source of water supply and kept normally closed by the pressure of said supply, and a second or flushing chamberconnected with the irst and also with the closet or basin to be ilushed, and means whereby the passage from the first chamber into the second and from the second chamber to the closet may be successively opened by the occupant of the closet,l all substantially as herein set forth.

2. In a flushing device for water-closets, urinals, and similar structures, the combination, with a water retaining chamber connected with the source of water supply, and having an outlet toward the closet, of a water-tight head or packing closing said chamber above the entrance of the water-supply, and a valve closing the outilow irom the said chamber toward the closet, the packing or head and the valve being connected by a common rod or piston, all substantially in the manner herein described and shown.

3. In a flushing device for water-closets, urinals, and similar structures, the combmation, with a water retaining chamber connected with the source of Water-supply, and a second or flushing chamber communicating with the iirst and also with the closet or urinal to be flushed, of a water-tight packing or pistonhead, F, and valves closing the passages between the chambers and from the flushingchamber to the closet, respectively, said piston-head and said valves being attached to a common stem, whereby they may be simulta neously moved or depressed, all substantially as and for the purposes herein set forth.

el. In a ilushing device for closets, urinals, and similar structures, the combination of the water-retaining chamber C and iiushing-chamber A, provided with a valved air-escape, a, of the piston-head F, provided with the valved air-passagef, the valves G and H, and the common valve-rod, E, attached to and carrying said piston-head and said valves, all substantially as herein described.

5. In a ilushing device for water-closets, urinals, and similar structures, the combination, with the communicating waterchambers C and A, of the rod E, carrying the piston-head F and valves G H, the lever I K, and the cord or connection L, extending to the closet or urinal to be flushed, all substantially as herein described.

6. In a llushing device for water-closets, urinals, and similar structures, the combination, with the communicating chambers C and A, of the piston-head F, valves G H, closing the passage between the chambers and the passage from the chamber A, respectively, said pistonhead and valve being mounted upon a common rod or support, E, the piston-headF and lower valve, H, being iiXedly attached. thereto, and the intermediate valve, G, being movably or adjustably attached thereto, all substantially as and for the purposes set forth.

In testimony whereof I have hereunto subscribed my name this 15th day of January, A. D. 188i.

HENRY C. WEEDEN.
